Question about Toshiba 46H84 46" Rear Projection HDTV-Ready Television

1 Answer

No picture, sounds fine. Fuse blown

The picture is blank on my tv and it keeps resetting itself as if the bulb was blown. I checked in the back and pulled out a unit that seems to contain the ballast and the bulb, I immediately saw a blown 2A fuse. I changed the fuse, the tv came on and worked for a minute and blew the fuse again. Ballast? Please help, thanks!

This set, I am sorry to say has no bulb and has no ballast circuit. There are three picture tubes inside this TV set. What exactly was the part you pulled out? Can you post a picture of the Part you pulled out?

LG 42PC!R Plasma TV turns on and then green led blinking with no ppicture and sound !

Your problem is most likely a fried circuit board. I always connect my good electronic to a back up battery. but your problem might have been storm or surge related, I would take it to a repair center and get an estimate.

TV will not turn on

Hi, It could well be the power supply that is in the back of your set. Have a repairman check it out. It's not a do it yourself thing. Good luck.

No picture

Have you tried checking the fuses this is a solution i posted a little while ago!!! I was watching tv there was a popping noise and screen went blank. My husbands very practical and we took the back off the tv ,we tested the fuses with a fuse tester and one had blown we took the fuse too Maplin our nearest electrical wholesaler who found us new fuses £1.29 for a pack of 10. We replaced the blown fuse now everything works as it should. Hope this helps we saved about £275 by doing it ourselves but do make sure you feel competent enough to have a go its not that hard but do make sure you unplugg the tv from the electric before you attempt taking off the back and checking the fuses and be careful as tvs can store a electric ok

Toshiba 43A61 Projection TV No picture, no sound

Two things to check on these when you get a black screen and only the power light, either a bad bulb or a bad fan. You can check the bulb, pull it out and get a meter and check for continuity across the two pins on the bulb, no continuity the bulb is blown. Also once you have the bulb out you will see the cooling fan in there, a vacuum and a air compressor to blow it out good is helpful. Check the bulb, clean it well, and try again. The blown fuse could also have been due to a stuck fan or blown bulb, i have seen the bulb blow and take out the fuse before on projection TV's, i have also seen cooling fans so full of dust and crud that they are stuck and drawing more amperage then they should and popping the fuse. I assume the 1.5a fuse that blew was on the mainboard inside? Some have an external fuse near the power cord input as well, but thats generally more then 1.5a.

Sony trinitron 32" just powered off by itself and won't turn back on.

Sounds like you all have a bad bulb that needs replaced.
This is a common problem.

Sony tv picture keeps flashing

You likely have bad solder connections around the tuner area. This model has a history of problems in that area or the tuner itself.
